Outlaw Sectors brings new maps and gameplay options to Sins of a Solar Empire: Rebellion

Outlaw Sectors DLC is here with a new gameplay option and lots of new maps

Challenge yourself with new strategies and unique setups with the new “Outlaw Sectors” gameplay option and brand new maps for Sins of a Solar Empire: Rebellion. The variety of map sizes and designs will let you enjoy any kind of match you want, from intimate 1v1 duels all the way to epic 10-player brawls.

Gameplay Options

The lawless fringe is increasingly hostile, but for those with a criminal mind it's also rich with new opportunities.

Smuggling Specialization: Choose this planetary development to grab a cut of everyone's trade income - but at a cost. The increased corruption from this black market activity will reduce that planet's tax income.

Rampant Militias: Autonomous planetary militias will grow, raid nearby systems, and repopulate over time. Use them to help defend your worlds, or coordinate your attacks with their strikes for maximum impact.

Pirate Turf: Vicious when in their home sector, pirates can now raid multiple players simultaneously, drastically changing the art of the bidding war. And, just to make sure they are fully motivated to do what they do best, all credits spent on bounties will receive an automatic bonus.

Included Maps
Power Struggle - Contest the distant resource fields and nearby planets before striking at the enemy’s homeworld.
Slim Pickings - Claim what remains among the war-torn stars and seize what you can from the other empires.
Crossfire - Take your enemy’s homeworlds and coordinate your assault with your ally in order to win.
High Stakes - Build a powerful fleet and seize the resource rich planets from enemy militia.
Ironheart - Flanked by an enemy on each side, you must prioritize your resources carefully to achieve victory.
Titans of Cimtar - Secure your planet from among the 8 gas giants dominating the map, then make war upon your neighbors.
Death Spiral - The system is falling into a black hole and your enemies aren’t about to let you leave without a fight.
Dogfight - Lead your allies into glorious battle amongst the stars in this huge map.
Buzzsaw - Make one mistake and you may lose more than you bargained for in this spiral galaxy that leaves no room for error.
Rising Empires - Secure your star system amidst the crushed local resistance and set your sights on your rivals’ territories.
Desolation - Claim what little the Vasari have left behind and forge what remains of the worlds in the massive cluster of stars into a force capable of conquest.

Outlaw Sectors DLC is now available on Steam or through Stardock.

About This Game

The Next Installment to the Award-Winning RTS.
While many were hopeful that diplomacy would finally end the war, differing opinions on what should be done, along with the depleted power of the controlling factions, has led to a splintering of the groups involved.

The loyalist members of the Trader Emergency Coalition adopt a policy of isolation, focusing on enhanced defenses to ride out the rest of the war. Those who rebel against the coalition take on a purely militant view, coming to the opinion that the only way to bring peace is by ultimately crushing all who oppose them - especially xenos.

For the first time in their history, the war creates a schism in the Advent Unity. The loyalists seek to continue their policy of revenge against the Traders, and to assimilate all others to the Unity’s influence. However, others amongst the Advent suspect that a corrupting influence from within has diverted the Unity from its proper destiny.

The divide created in the Vasari Empire is less pronounced, but just as severe to their people. With the Vasari now practically frantic to move on to new space, the loyalist faction abandons cooperation and decides to take the resources they need by any means necessary. Having accepted the need to work together, the rebel faction feels that their best chance for survival is to work with the other races and bring them along to flee the approaching enemy.

Take the battle for galactic supremacy to its ultimate level in Sins of a Solar Empire: Rebellion – a standalone RT4X game that combines the tactics of real-time strategy with the depth of the 4X genre (eXplore, eXpand, eXploit, eXterminate).

Key features:

  • New Factions: Decide whether to play as a Loyalist or Rebel – each unlocks new technologies, ships and play styles for each race.
  • New Titan Class Warships: Mighty titans enter the fray of the war to tip the scales of power. Each faction may field their own unique titan, drawing upon unique strengths and abilities on the battlefield.
  • New and Updated Capital Ships: A new capital ship joins the fleet for each race to offer even more tactical options. Additionally, all existing capital ships have been upgraded to four levels for their abilities, allowing players to focus their ships along specific strengths.
  • New Corvette Class Ships: Small and maneuverable, each faction has developed a new light attack craft to harass enemy forces.
  • Updated Visuals: Updated graphics, particle effects, lighting and shadows, race specific UI and other enhancements make the Sins’ universe look better than ever.
  • New Victory Conditions: Take multiple paths to victory including – Military, Diplomatic, Research, Last Flagship Standing, Last Capital Standing and Occupation.
  • New Audio: More than 60 minutes of original music, countless new sound effects and dozens of new voice overs help bring the drama of battle to new levels of immersion.
  • Tutorials: New and updated tutorials make it easy for both experienced and new players to quickly start building their own solar empire.
  • Plus, a number of optimizations that provide better performance than ever before!

My best memory, played this game with my friends for 8+ hours each time. Every stage of this game is fantastic, early exploring stage, middle developing stage, late battle stage. You need to be patient and better play this during weekends without plans XD

Just want to say this game is one of the best that I have ever played! Its design and gameplay is just perfect. The level of detail on a game of this scale is brilliant! One thing I will mention is the lack of Steam Workshop support, but with a bit of patience and a quick look on the web, you can find loads of tutorials on installing the many mods that are available.
I personally play Sins with a total conversion mod called Star Trek: Armada 3. Anyone who is a Trek fan, I highly recommend that you give it a try. Heres the link to the webpage:
Also there is a Star Wars mod. Thanks for reading and I hope you love the game like I do!!

This is the PC game that forced me to go out into the world and purchase my own PC. Before Sins of a Solar Empire, the only games I played on the computer were over at a friends house, but after week long (game time) sessions of play in a SINGLE match of Sins, I was hooked. This game has the depth and micro-managing features I crave, with a sleek enough system of menus that, after a small learning curve, never slows the pace of battle/building/expanding my space empires. The only thing I'm ever left craving from Sins of a Solar Empire is MORE Sins of a Solar Empire.

One of the best of its breed. Plus with all the sweet mods out for it, Sins can scratch your itch for all sorts of brands; Star Wars, Star Trek, Halo, etc. But hey, the base game is awesome all by itself too.

-Made a game where I was alone against 7 AI players.
-Managed to build 6 capital ships and kept them alive while destroying 7 or 8 enemy capital ships and a truckload of frigates and cruisers.
-Watched in horror as my entire fleet was slaughtered by one Vasari Starbase.

I've had this game for years and I never get tired of playing it. Now I just learned how to apply MODs and it is even that much better. I love the Star Trek Armada 3 MOD and have been playing it for a few months now.

I've had this game for so long now. Every now and again I even google to see if they will ever make a 2nd one. The gameplay is so deep and fun. You really feel like this could be the future! You can zoom out and see the galaxies at your disposal and zoom back in the see the fighters fending off the enemy. I get so much enjoyment out of the game, HOWEVER!

I have played this game on multiple computers, all very high end gaming machines. Quad Cores, i7s... Radeon 7990's ect. These machines are made to game... But this game is not made to game. You can do so much but at the same time you are limited by old software. I have never been able to play a full game with more then 80 planets (which in this game is not a lot)

I find myslef always having to play short small games, anything large you will start lagging maybe only an hour into the game. There is so much potential here and it is still fun but I think the game has past its time and the developers really need to create a new one from scratch that is capable of taking advantage of my machines and giving me a incredible gameplay experiance.
